This device is quite unique in the stereo Bluetooth world because it’s convertible. You can have it in stereo or if you prefer a mono headset you just need to detach one of the earbuds. It’s equipped with AudioIQ DSP noise reduction technology for MP3 mobile phones and it’s the lightest stereo Bluetooth headset up to date at just 15 grams. Also, it offers up to 7 hours talk time from a single charge and 160 hours standby time
